CAR COUPLI'NG.

SPECIFICATION forming part of Letters Patent No. 263,213, dated August22, 1882.

Application filed July 5, 1882. (N0 model.)

To all whom. it may concern:

Be it known that I, AROHIBALD A. PORTER, of Griflin, in the county ofSpalding, and in the State of Georgia, have invented certain new. anduseful Improvements in Gar-()ouphugs; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of .referencemarked thereon, making a part of this specification. I

This invention relates to certain improvements in car-couplers andmechanism for operating the same; and ithas for its objects to providefor automatically coupling the cars and for uncoupling the same withoutnecessitating the entrance of a person between the same for the purposeof preventing accidents. These objects I attain by the mechanismillustrated in the accompanying drawings, in which- Figure 1 representsa sectional view, showing two drawlleads with .the coupling-pins inelevated and dropped positions, respectively. Fig. 2 represents ahorizontal section of one of the draw-heads; and Fig. 3 represents anend elevation of a car, showing my coupler and the mechanism foruncoupling.

1 The letterAindicates the draw-heads, which are constructed with theusual flaringtmouths, and are chambered for the reception of the movableslides B. These-slides at their forward ends are formed, as indicated inFigs. l and 2, with a depression on top and a recess at the forwardedge. The said slides are recessed at their rear ends for the receptionof aspiral spring, (J, which bears at the'rear against'a pin, D, whichserves, in connection with a link, E, and pin F, to hold the shdeinplace and at the same time permit it to play.

The pin has a head at its top, under which sits the bent slot-ted end ofan upright bar, H, which is provided with a pin, I, extending throughslots Kin the levers L, which are fulcrumed to the end of. the car at M.The 30 the rope is drawn upon and the short arm of the lever isdepressed. The slides at their forward ends are provided with undercutrecesses P, which serve to hold the link in a horizontal position in onehead when the cars are approaching each other. In coupling the cars theparts are arranged as shown in Fig. 1, and upon the links entering thehead at the left of said figure the slide is thrown back, automaticallyeffecting the coupling. To uncouple it is only necessary to draw uponthe levers at either side of the car to release the couplingpin. Bymeans of the rope extending to the locomotive the cars may be uncoupledby the engineer without stopping the train.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, 1s-

1. In combination with the draw-heads, the movable slides, constructedas described, and recessed at their rear. portions, the spiral springssitting in the recessed portions, the

links extending longitudinally through said springs, and the pinsextending through the slides and the draw-head, respectively, and alsothrough the links, substantially as and for the purposes specified.

2. In combination with the coupling-pins, connecting-bars, and slottedlevers, the rope and spring, and the pulley under which such ropepasses, substantially as and for the purposes specified.

In testimony whereof I affix my signature, in presence of two witnesses,this 6th day of June, 1882.
